if your VRML has the model split into different parts OpenSG will
normally retain that hierarchy. In that case you basically only need to
find the parts in the scenegraph. This can be done by naming the parts
in the VRML file, OpenSG will put these names as NameAttachments on the
corresponding nodes (you can use the functions getName, setName to
access/modify the value of a NameAttachment).
If your VRML only contains a single geometry, I guess your best bet is
to go back to the modeling program you used and try to have it export a
hierarchy of objects instead. Doing this inside OpenSG is probably a lot
more work, especially if you do not turn of the striper (it runs by
default to speed up rendering of geometries. Pass a different GraphOpSeq
to SceneFileHandler::the().read("filename", graphopseq), or just NULL).
Hope it helps,
Carsten
